Conventional lithium-ion batteries (LIBs) based on organic liquid electrolytes are limited to an operation temperature range of approximately −20 to +50 °C, mainly due to electrolyte decomposition and associated safety hazards, such as thermal runaway. All-solid-state batteries (ASSBs) provide inherent safety benefits but remain constrained by the limited temperature adaptability of solid electrolytes (SEs). Here, we address this challenge through a high-entropy design strategy, developing a high-entropy amorphous oxyhalide SE (Li1.6Ta(PSiB)0.15O1.65Cl5Br0.1) that incorporates three synergistic features: (1) high-entropy multication mixing (Ta5+/P5+/Si4+/B3+) creating efficient ion-conduction pathways, (2) mixed-anion engineering (O2−/Cl−/Br−) lowering ionic migration barriers, and (3) the incorporation of non-metallic cations (P5+/Si4+/B3+) improving reduction stability, all within an amorphous framework that suppresses interfacial degradation. The optimized electrolyte exhibits an exceptional ionic conductivity of 7.1 mS cm−1 at 25 °C alongside enhanced electrochemical stability. ASSBs fabricated with this high-entropy SE, a single-crystalline LiNi0.8Co0.1Mn0.1O2 (scNCM811) cathode, and a Li–In anode demonstrate outstanding wide-temperature-range-operation performance. An 82% capacity retention is achieved after 2400 cycles at 2C and 25 °C, with an ultra-low fading rate of 0.007 mAh per g per cycle. Zero capacity fade over 100 cycles at −30 °C and 80% capacity retention following 1300 cycles under 10C fast charging at 60 °C are demonstrated.

As a pivotal technology for high-level liquid waste (HLW) treatment, vitrification plays a crucial role in ensuring the sustainable development of nuclear energy. The two-step vitrification process, which involves initial calcination of HLW into solid calcine followed by melting with base glass, has demonstrated significant improvements in immobilization efficiency. This study investigated the capacity of simulated HLW calcine to be incorporated within a borosilicate glass matrix.Through comprehensive characterization techniques including field emission scanning electron microscopy coupled with energy dispersive spectroscopy (SEM-EDS), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and Raman spectroscopy, the effects of calcine content (18-32 wt%) on the microstructure, chemical composition, phase distribution, and network structure of the vitrified matrixs were examined. Homogeneous glass matrices are achieved at 18–26 wt% calcine content, while phase separation and crystalline precipitation occur at higher concentrations. However, when the content reaches 28 wt%, the initial precipitation of granular CaMoO 4 crystals occurs, maintaining relatively uniform distribution. Further increasing the content to 30 wt% leads to the formation of acicular CaMoO 4 phases accompanied by minor Zr x Ce 1-x O 2 particle precipitation. Notably, at 32 wt% calcined product content, a distinct phase separation layer emerges on the surface of the vitrified matrix, with a substantial increase in Zr x Ce 1-x O 2 precipitates. These research findings have clarified the incorporation capacity limits of simulated HLW calcine in borosilicate glass matrix, providing valuable theoretical guidance for enhancing waste loading in vitrified forms during the vitrification process.

Shear stiffening gel (SSG) with prominent rate-dependent mechanical properties is promising for impact protection, but conventional boron-based SSG suffers from toxicity and corrosion arising from boric acid. Here, we design a boron-free supramolecular dynamic reversible network of polytitanosiloxane (PTS) based on the metal-ion-mediated hydrogen bonding enhancement strategy. Different oxidation states of Ti atoms in the network influence the charge distribution of the adjacent hydroxyl groups (Ti-OH). The electrostatic potential of the H-bond donor and acceptor could be effectively modulated by the Ti 4+ and Ti 3+ cations, thereby enhancing the H-bond strength. The resulting PTS SSG exhibits exceptional shear stiffening (~2800 times, 0.1–100 Hz), negligible corrosion, and low cytotoxicity (Grade 1). The PTS SSG is further explored for impact protection materials and flexible mechanical sensors in practice. The hydrogen bonding enhancement strategy also paves the way for developing dynamic reversible networks to fabricate next-generation smart materials.

This study presents the development and comprehensive characterization of biopolymer-based nanofibrous composites composed of polyvinyl alcohol (PVA), chitosan (CS), boric acid (BA), and a natural antifungal agent natamycin (NAT), designed for therapeutic applications. A dual-layer 3D-fiber composite (PVA/CS/BA_PVA/NAT) was successfully fabricated using a layer-by-layer 3D bioprinting technique and electro-spinning, integrating BA into the core matrix and NAT into the outer layer. Mechanical tests revealed a significantly improved elastic modulus of 763.04 ± 14.54 MPa and the highest ultimate tensile stress (50.45 ± 2.58 MPa) among all samples. Despite a moderate strain at break (11.77 ± 0.49%), the composite preserved sufficient elasticity suitable for biological interfaces. Morphological assessment via SEM confirmed the successful deposition of continuous and bead-free nanofibers, with controlled fiber alignment and reduced average fiber diameters, especially in the BA-incorporated structure. The dual-layered system displayed enhanced uniformity and structural coherence. The drug release analysis demonstrated sustained NAT delivery over a 90 min period. Kinetic modeling showed a high correlation with the Korsmeyer–Peppas model (R2> 0.99), suggesting diffusion-controlled release, supported by the Korsmeyer–Peppas model’s Fickian diffusion exponent. In contrast, zero- and first-order models exhibited weaker fits, underscoring the relevance of a matrix-based release mechanism governed by the layered configuration. Crucially, antifungal assays againstCandida albicansrevealed substantial bioactivity. The PVA/CS/BA_PVA/NAT formulation achieved the largest inhibition zone (1.64 ± 0.13 cm), significantly outperforming single-layer controls such as PVA/CS/BA (1.25 ± 0.08 cm) and PVA/CS_PVA/NAT (1.43 ± 0.08 cm), while neat PVA exhibited no inhibition. These results confirm the synergistic antifungal efficacy of BA and NAT within the dual-layer structure. Together, these findings highlight the potential of the 3D-printed PVA/CS/BA_PVA/NAT composite as a mechanically robust, morphologically optimized, and bioactive platform for antifungal therapy and wound-healing applications.

Achieving both high durability and low ice shear strength in intrinsic-lubricated anti-icing coatings (without lubricant) remains challenging. This work fabricates a lubricating polymer copolymerized from polyborosiloxane and polyfluoroacrylate via dynamic boron oxygen bonds, where the reversible cleavage/reformation of boron oxygen bonds endow the surface with dynamic mobility and polyfluoroacrylate reduces surface energy. The resulting PFBS coating delivers an ultra-low ice shear strength (1.0 ± 0.1 kPa), excellent durability under harsh conditions (Δτ ≤ 1.3 kPa), and the ability of complete repair at −20 ℃. This study clarifies the synergistic mechanism of B–O bonds and PDMS segments in boosting anti-icing performance and durability, offering a new design strategy for high-performance anti-icing coatings.

Engineering the electronic structure via heterojunction construction and morphological control effectively advances electrocatalysis. A dendritic porous FeCoNiP@HEAs Mott-Schottky heterojunction is fabricated by electrodeposition as bifunctional catalysts. The heterojunction modulates the electronic structure, optimizing the adsorption energy of reaction intermediates. The superhydrophilic/superhydrophobic surface minimizes bubble adhesion, while the dendritic tip architecture enriches electrolyte-active site contact. Consequently, the FeCoNiP@HEAs electrode exhibits outstanding activity and durability. In alkaline electrolyte, overpotentials for OER and HER are only 205 mV and 152 mV at 100 mA cm −2 , respectively. The two-electrode cell achieves stable overall water splitting at 1.66 V for 60 h at 100 mA cm −2 . XPS confirms that the heterojunction effectively regulates the interfacial electronic structure, with stronger modulation for phosphide/HEA composites than for phosphide/ternary alloy counterparts. High-valent metal ions further enhance performance. DFT calculations verify the Mott-Schottky heterojunction, which optimizes d-band center, reduces adsorption energy, accelerates interfacial electron transfer, and boosts catalytic activity.

Ziconotide (ZIC) is an N-type calcium channel antagonist for treating severe chronic pain that is intolerable, or responds poorly to the administration of other drugs, such as intrathecal morphine and systemic analgesics. As it can only work in the brain and cerebrospinal fluid , intrathecal injection is the only administration route for ZIC. In this study, borneol (BOR)-modified liposomes (LIPs) were fused with exosomes from mesenchymal stem cells (MSCs) and loaded with ZIC to prepare microneedles (MNs) to improve the efficiency of ZIC across the blood-brain barrier. To evaluate local analgesic effects of MNs, the sensitivity of behavioral pain to thermal and mechanical stimuli was tested in animal models of peripheral nerve injury , diabetes-induced neuropathy pain, chemotherapy-induced pain, and ultraviolet-B (UV-B) radiation-induced neurogenic inflammatory pain . BOR-modified LIPs loaded with ZIC were spherical or nearly spherical, with a particle size of about 95 nm and a Zeta potential of −7.8 mV. After fusion with MSC exosomes, the particle sizes of LIPs increased to 175 nm, and their Zeta potential increased to −3.8 mV. The nano-MNs constructed based on BOR-modified LIPs had good mechanical properties and could effectively penetrate the skin to release drugs. The results of analgesic experiments showed that ZIC had a significant analgesic effect in different pain models. In conclusion, the BOR-modified LIP membrane-fused exosome MNs constructed in this study for delivering ZIC provide a safe and effective administration for chronic pain treatment, as well as great potential for clinical application of ZIC.

CaCO 3 /CaO thermochemical energy storage based on concentrated solar power plant is a promising technology because of its high working temperature and energy storage capacity. Papermaking white mud (PWM) from paper mill is a potential CaO-based precursor due to its high content of CaCO 3 . Herein, a novel Ca 3 B 2 O 6 -modified PWM was synthesized to examine its thermochemical energy storage performance. The influences of the types and dopant amounts of B 2 O 3 precursors on the energy storage capacity of Ca 3 B 2 O 6 -modified PWM were discussed. The stable Ca 3 B 2 O 6 -modified PWM with the mass ratio of CaO to Ca 3 B 2 O 6 = 88:12 exhibits superior energy storage performance and heat transfer property during CaCO 3 /CaO cycles. The effective conversion and energy storage capacity of Ca 3 B 2 O 6 -modified PWM are approximately 0.67 and 2129.6 kJ/kg at 31st cycle, respectively, which are 2.48 and 1.76 times as high as those of PWM and pure CaCO 3 , respectively. The introduction of Ca 3 B 2 O 6 improves the sintering resistance and thermal conductivity of PWM, resulting in higher cyclic stability and lower decomposition temperature of CaCO 3 . Ca 3 B 2 O 6 enhances the basicity and improves the strong basic sites of PWM, which is beneficial for the adsorption of CO 2 , leading to greater CO 2 adsorption capacity. Moreover, Ca 3 B 2 O 6 increases the oxygen vacancy concentration of PWM, which is conducive to the diffusion of O 2– and production of CO 3 2– , further improving energy storage capacity. Hence, Ca 3 B 2 O 6 -modified PWM seems to be a suitable energy storage material for the CaCO 3 /CaO process.

Accurate, rapid, and sensitive pathogenic detections play an important role in food safety. Herein, we developed a novel CRISPR/Cas12a mediated strand displacement/hybridization chain reaction (CSDHCR) nucleic acid assay for foodborne pathogenic colorimetric detection. A biotinylated DNA toehold is coupled on avidin magnetic beads and acts as an initiator strand to trigger the SDHCR. The SDHCR amplification allowed the formation of long hemin/G-quadruplex-based DNAzyme products to catalyze the TMB-H2O2 reaction. In the presence of the DNA targets, the trans-cleavage activity of CRISPR/Cas12a was activated to cleave the initiator DNA, resulting in the failure of SDHCR and no color change. Under optimal conditions, the CSDHCR has a satisfactory linear detection of DNA targets with a regression equation Y = 0.0531*X – 0.0091 (R2 = 0.9903) in the range of 10 fM to 1 nM, and the limit of detection was determined as 4.54 fM. In addition, Vibrio vulnificus, one foodborne pathogen, was used to verify the practical application of the method, and it showed satisfactory specificity and sensitivity with a limit of detection at 1.0 × 100 CFU/mL coupling with recombinase polymerase amplification. Our proposed CSDHCR biosensor could be a promising alternative method for ultrasensitive and visual detection of nucleic acids and the practical application of foodborne pathogens.

In this study, CaO–B 2 O 3 –SiO 2 (CBS) glass–ceramics were prepared and compounded with different contents of ZrSiO 4 . The sintering behavior, phase composition, microstructure, dielectric properties, thermal properties, and mechanical properties of this CBS glass–ceramic composite ZrSiO 4 ceramic system were investigated. The results show that CBS glass–ceramic can be sintered densely at 750 °C. However, the crystallinity is unexpectedly low and the dielectric properties are greatly damaged. Surprisingly, the addition of ZrSiO 4 improved the dielectric constant of the composites and achieved a dielectric adjustable in the range of 6.0–7.8. When the composite was sintered at 830 °C for 15 min with 35% ZrSiO 4 addition, the bulk density of the composite increased to 2.93 g/cm 3 . The dielectric constant measured at a high frequency of 13 GHz was 6.93 and the dielectric loss of 1.66 × 10 –3 . Accordingly, the addition of ZrSiO 4 reduced the thermal expansion coefficient of the composite to 6.1 ppm/°C and increased the flexural strength of the composite to 248 MPa.

Ba1.09Pb0.91Be2(BO3)2F2 (BPBBF), a previously unreported lead-containing beryllium borate fluoride, has been successfully grown through a high-temperature flux method. Its structure is solved by single-crystal X-ray diffraction (SC-XRD), and it is optically characterized via infrared, Raman, UV–vis–IR transmission, and polarizing spectra as well. SC-XRD data suggests that it can be indexed by a trigonal unit cell (space group P3m1) with lattice parameters a = 4.7478(6) Å, c = 8.3856(12) Å, Z = 1, and V = 163.70(5) Å. This material could be considered as a derivative of the Sr2Be2B2O7 (SBBO) structural motif. It consists of 2D [Be3B3O6F3]∞ layers in the crystallographic ab plane, with divalent Ba2+ or Pb2+ cations serving as spacers among the adjacent layers. Ba and Pb were found to adopt a disordered arrangement in the trigonal prismatic coordination within the BPBBF structural lattice, which is evidenced by both structural refinements against SC-XRD data and energy dispersive spectroscopy. The UV absorption edge (279.1 nm) and birefringence (Δn = 0.054@ 546.1 nm) of BPBBF are confirmed by UV–vis–IR transmission and polarizing spectra, respectively. The discovery of this previous unreported SBBO-type material, BPBBF, along with other reported analogues such as BaMBe2(BO3)2F2 (M = Ca, Mg, and Cd), provide a prodigious example for tuning the bandgap, birefringence, and short UV absorption edge via simple chemical substitution.

Traditional Fe(VI) treatment process does not fully utilize the fresh iron flocs. This study proposed a novel Fe(VI) flocs recycling process. The flocs were recycled into the front-end reactor and the flocculation effluent further reacted with Fe(VI). Compared with Fe(VI) alone, the COD Cr of the secondary effluent of hospital wastewater decreased from 74.9 to 59.4 mg/L and TP decreased from 0.36 to 0.10 mg/L at the dosage of 20 mg/L Fe(VI). However, the enhanced removal of NH 3 -N and TOC by the flocs recycling process is limited. The Fe(VI) flocs recycling process also strengthened the removal of luminescent bacterial acute toxicity, from 0.52 ± 0.01 in secondary effluent to 0.17 ± 0.01 mg-ZnSO 4 /L. Compared with polymeric ferric chloride and ferric chloride (FeCl 3 ), Fe(VI) showed the best performance on purifying wastewater in the flocs recycling process. Compared with FeCl 3 , the C O bond contents in flocs from Fe(VI) changed more obviously. Flocs from Fe(VI) have a smaller average particle size than those from FeCl 3 , which may result in better adsorption capacity of Fe(VI) flocs. In conclusion, the flocs recycling process not only taken full use of the Fe(III) flocs and reduced the iron sludge, but also strengthened the purification of the wastewater without additional Fe(VI) dosing.
